how about stopping the cluster, then copy data from the directory to a new location. After that mounting a new partition to the old directory?
Anyway, re-mounting should work with keeping in mind the file structure should be
preserved and file access as well.
In case you need assitance, don't hesitate to contact with our support guys!
I was asking if the BIG data files (/opt/dtmanaged/data/server, /opt/dtmanaged/data/Cassandra and /opt/dtmanaged/data/elasticsearch) can be stored at another location e.g. /var/spool/dtmanaged/data* and all other binaries and log files kept in the same location as before (/opt/dtmanaged/*). The installation is already complete and the cluster is up since 1 year.
We wanted to allocate higher storage to /var/spool/dtmanaged and keep the BIG data files there without disturbing the Dynatrace binaries and log files that would continue to be in /opt/dtmanaged/* folders.
Is there any way, this can be done? We tried to change cassandraDatastoreDir in config.properties file and restarted the service but it still kept writing to the old location.
